I was out looking at it last night. I thought it was kinda a overblown, but I can tell you about an hour after dark, areas of the moon DID look pale blue (Not the whole moon).
IT was the flat areas that appeared blue. I cannot explain why.
My wife and I were out for a walk. It really is worth seeing.
The full Moon appears to be ‘blue’ when at zenith, because the atmosphere of the Earth scatters the blue wavelengths of light more than the red or yellows.
That is also why it appears red or orange at the horizon due to dust and smoke particles in the line of sight scattering the red and orange wavelengths more.
Also, the large flat areas of the Moon appear ‘blue’ because they are reflecting the indirect light from the Earth which is primarily bluish, the sky is blue on the sunlit side.
When an Eclipse of the Moon occurs, it moves into the Earth’s shadow and so appears darker reddish or even brown.......................
I thought it was called a blue moon when it was the second full moon for any particular month.
There was a full moon on Aug 1.
